I just discovered an interesting new service called Slashdoc Beta, which appears to be a content repository similar to Google Base. However, the data appears to be less structured and the focus is on submitting your old essays. From the Slashdoc site:
Slashdoc is the place to put all the documents you have sitting on your computer that you think are useless. Those include old school papers, essays, and research projects. Or once which are valuable but are not getting enough exposure. Those may be your resume, poetry or creative writing. Anything goes! We will accept anything as long as it's not illegal, of adult nature, or blatant spam.
We use the latest technology to make sure your documents are submitted to the major search engines giving you the most exposure possible. Everything is completely free, and you maintain copyright to your work. Next time somebody types in your name into Google, make sure they see your best work.
